ABSTRACT:
A door security device for enhancing structural integrity between a door and a doorjamb includes a generally U-shaped door reinforcing member, a reinforced striker plate, and securing members. The door security device may be installed on a door including a door latching device and having a bolt member selectably movable within the doorjamb to secure the door to the doorjamb when the door is closed. A cut-out within the end plate of the door reinforcing member has at least a selected vertical height, and the reinforcing member and striker plate are mounted to the door and doorjamb, respectively, such that the striker plate is received within the cut-out when the door is closed without the latching plate overlapping the end plate of the door reinforcing member. Since the edge of the door is closely adjacent the doorjamb and striker plate, the door reinforcing member may be stamped from relatively thick stock having a substantially uniform thickness, thereby reducing manufacturing costs.
